Definitions

  • This patent application refers to an automatic locking device for shutters in fully open position.
  • the device is designed to be fixed on the external wall of buildings and used to hold window or door shutters in place in fully open position, in such a way that shutters cannot accidentally close because of wind or get damaged because of repeated shocks, at the end of the opening or closing travel, when shutters are uncontrollably closed or opened by wind or strong air drafts.
  • the device that is the object of this patent application belongs to the second group, since it is automatically activated thanks to the presence of articulated elements that receive and use the push of the shutter at the end of the opening travel, when the shutter surmounts the device and touches the external wall of the building.
  • the articulated elements do not obstacle the passage of the shutter during opening, although they prevent the shutter from travelling backwards and closing.
  • the articulated elements are normally submitted to a return force that makes them stable in idle position, which coincides with the position assumed by the articulated elements to lock the shutter at the end of the opening travel.
  • the return force is normally exercised by elastic members or counterweights that act on the articulated elements.
  • Patent EP 0823524 devises an automatic locking device for shutters, in which the shutter is locked inside a forked bracket that oscillates around an horizontal pin and is subjected to the push of an elastically flexible arched plate that holds the bracket in locking position.
  • Patent EP 0119413 devises an automatic locking device for shutters, in which the shutter is locked by an element that oscillates around an horizontal pin and is subjected to a counterweight that holds the element in locking position.
  • the purpose of this invention is to provide a solution to the aforementioned drawbacks by devising a new automatic locking device for shutters in fully open position, which is composed of a few, simple elements, without the need of using elastic members, counterweights, screws and hinges.
  • Another purpose of this invention is to devise an automatic locking device for shutters in fully open position, which is composed of elements with simple geometrical configuration that can be produced easily and economically.
  • the last purpose of this invention is to devise an automatic locking device for shutters in fully open position, which is composed of a few elements that can be assembled easily and rapidly also by non-specialised workers without the use of special expensive machinery.
  • the device of the invention comprises a support bracket provided with a threaded rod for wall fixing, a tubular cursor that is inserted and slides outside the support bracket, a collapsible bascule element pivoted at the front end of the cursor, with a fixed counter-element that projects from the back end of the cursor.
  • the point of the support bracket is shaped in such a way that it advantageously co-operates with the base section of the collapsible element, normally in lowered position, which is automatically raised in vertical position when the tubular cursor is forced to slide backwards along the support bracket due to the push exercised by the shutter on the counter-element, when the shutter reaches the end of the opening travel.
  • the collapsible element must be lowered in horizontal position to close the shutter and the backward downward rotation of the element is only possible if the element is moved away from the point of the support bracket.
  • the device of the invention comprises a support bracket (1) provided with a threaded rod (2) for wall fixing, a tubular cursor (3) that is inserted and slides outside the support bracket (1), a collapsible bascule element pivoted at the front end of the tubular cursor (3), with rectangular cross-section that exactly matches the cross-section of the central body (1a) of the support bracket (1).
  • the front of the support bracket (1) ends with a thinner section (1b) joined to the central body (1a) by means of a right step (1c).
  • the point (1d) of the ending section (1b) has a profile with rounded off corner.
  • the front end of the tubular cursor (3) has a notch (5) affecting the upper wall only (3a) and having the same (or higher) depth as the length of the ending section (1b) of the support bracket (1).
  • the collapsible element (4) is housed and pivoted inside the front end of the tubular cursor (3) by means of a transversal pin (6) inserted into two holes (7) located on the vertical walls (3b) of the cursor (3) and into one hole (8) located near the base of the collapsible element (4) that in vertical position is exactly housed inside the notch (5).
  • the support bracket (1) is hollow in a long section of the upper border, thus forming a thin section of support bracket (1e), on which the screw (2) is applied, being joined to the body (1a) by a right step (1f) designed to engage - during the forward travel of the tubular cursor (3) - with a matching bar (9) that goes across the cursor (3) near the back end, from which a fixed counter-element (10) projects, with a downward projecting knob (11) near and below the front end.
  • the collapsible element (4) When the shutter is opened, the collapsible element (4) must be in lowered position, and the cursor (3) must be in maximum forward position with respect to the support bracket (1), as shown in Fig. 1 .
  • the element (4) can move forward (as shown by F4) to a perfectly horizontal position, as shown in Fig. 6 .
